btw can extreme chaos be used on Shisui?

Guys... are you trolling or talking out of ur ... ? What Kakashi Kimono removing? Shisui can't be debuffed like 6p Pain so what debuff are you going to apply on him dude? Typical forum experts, saw ninja only on youtube, has no idea how he works but first to comment.

As for Obito it's plain impossible as well, you are dead round1 (at least your backline most of the time is) and round 2 unless guy has 0 IQ he just kills this time backline for sure or to be safe locks Obito mystery (not to mention that you have to trigger Shisui's dodge first too yeah good luck with this idea) so your perfect easy counters to "everything has a counter" simply don't work.

FelineSeven is sadly right,

this time there is no counter to Sus Shisui. He is so broken that they covered everything. There are only 2 ways right now to win vs somewhat equal power Shisui with out using him yourself:

1) BT Danzo Izanagi 1shot team (needs strong backline so with hidden buff shisui cant easly lock your mystery r2)

2) Base Hiruzen with pos1 Edo Zabuza who at least can do something with his own multiple standard attacks since we cant use mystery at all.

Special reward to Teemonly, trying to sound smart with 0 knowledge about the game always brings good laugh.
